The problem with statistic is simple, in here if you end up in hospital, suddenly die ans death and they find out you have been infected in covid - they often write that cause of death was covid infection. There was huge butthurt about that, because they should only count respiratory failures or other symptoms strictly related to covid as such, but they ended up adding people with heart attack or strokes into those. Those also could be caused by covid, but possibility is much lower.
Anyway, average age of death by covid in Poland was 72.9, so I doubt any of us will have serious problems. Omicron on statistics despite having infected much bigger amount of people than Delta, had lesser lethality.
I was unvaxxed and fully recovered in 3 days.
